The study of electric dipole moments (EDMs) offers a unique window into the violation of time-reversal symmetry, an effect that, when coupled with charge-parity (CP) violation, presents fundamental ...

Incompatible moments A spinning charge (left) acts like a loop of current to produce a magnetic dipole moment (blue arrow). Distorting the electron's charge distribution (middle) produces an electric ...

The most precise measurement yet of the electron’s shape casts doubt on ideas such as supersymmetry that predict a zoo of undetected particles in the universe Scientists are unanimous that their ...

Monitoring precession: The researchers measured the electron electric dipole moment in hafnium fluoride ions confined within an ion trap. (Courtesy: Casey Cass/University of Colorado) One way to look ...
